A millimeter-wave sample and hold (S/H) mixer with LO duty cycle control is developed using 22 nm Fd-SOI CMOS technology. A direct rF undersampling receiver using an S/H mixer has been reported to achieve a small area and low power consumption. In this architecture, a timing control circuit is required to synchronize the hold period of the S/H mixer with the sample period of an analog-to-digital converter (AdC). The proposed S/H mixer allows the adjustment of the LO duty cycle by varying the gate bias voltage of LO buffers, which mitigates the resolution of the timing control circuit. The fabricated S/H mixer achieves a measured conversion gain of greater than -15 dB and measured EVM of <2 % for 400 MS/s 64QAM in the 33–51 GHz range.

Number theory algorithms are extensively required for many digital signal processing (dSP) systems. Over the last few decades, the science community has been discovering the practical applications of number theory. High-speed number manipulation for arithmetic operations is a key component in dSP *** that alternative arithmetic hardware may find a niche. This work consists of designing FIr filter using residue number system and Logarithmic number system. Also, proposed novel rLNS scheme based on the merging of rNS and LNS. Compared to other number systems, the residue Logarithmic Number System (rLNS) offers faster operation and more precision. Our prior work explains the creation of the Fixed-width multiplier utilizing the rLNS multiplier as well as the performance evaluation. Because of its distinct area and power compactness qualities, the fixed-width multiplier has been *** the Fixed-width multiplier has its attractive characteristics, it has a limitation of producing truncation error. Additionally, the truncation error was effectively decreased by 89% using the Taylor series expansion for the error approximation, which is significantly less than the orthodox truncated multiplier. The expansion of the earlier work is presented in this paper. The digital FIr filter uses a fixed-width multiplier that is based on rLNS *** the implemented FIr filter can be used for many image or video processing applications. The filter co-efficient has been processed via Fast Fourier Transform (FFT) considered a complicated algorithm for complex numbers. Finally, the comparative analysis of designed filter using rNS, LNS and rLNS has performed. From the investigation, we conclude that the proposed novel rLNS algorithm provides high performance for dSP *** parameter signal-to-noise (SNr) ratio is very significant to measure the value of the precision of the proposed filter. If the SNr value is higher than 25 dB, the filter performs

Traffic flow parameter forecasting is the basis for the traffic control and optimization, which plays a very significant role in actual traffic scenarios. When taking the daily traffic flow parameters as the research object, the daily traffic flow patterns on holidays are often quite different from that on non-holidays. Therefore, it is important to capture the correlation between traffic flow parameters and holidays. However, in recent years, most research on daily traffic flow forecasting is only based on simple deep learning methods, and do not consider the relationship between traffic flow parameters and holidays. Meanwhile, the daily traffic flow patterns during holidays and non-holidays are not necessarily different. In this paper, we put forward a novel method for daily traffic flow parameter forecasting, taking the influence of holidays into account. Basing on the deep learning method composed of convolutional neural network and long short-term memory (CNN-LSTM), we combine the traffic flow pattern with various external factors. While considering the influence of holidays, we incorporate the "holiday special or not" feature extracted from the traffic flow parameter data itself to realize the daily forecasting. The forecasting method put forward shows good accuracy on case-testing. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Electrochemical impedance spectroscopy (EIS) is a non-invasive tool capable of characterizing batteries' states based on impedance over a specific frequency range. Considering that the use of lithium-ion batteries with large capacity in many electric vehicles imposes an extremely high impedance measurement accuracy in a range of sub-mΩ, EIS systems widely use a digital lock-in amplifier (dLIA) that allows ultra-precision impedance measurement at the cost of a long settling time. This work presents an onboard EIS system with further reduced measurement time. In the proposed EIS system, the dLIA embedding of a pair of quasi-linear-phase band-pass filters is utilized to shorten the settling time by widening the bandwidth of the noise suppression low-pass filter with minimum accuracy degradation. Compared to the EIS systems using the conventional dLIA, this work achieves a 45% and 57% reduction in the estimated settling time over the frequency range of 1-to-1000 Hz and at the lower bound (1 Hz), respectively.

Background: All-solid-state batteries (ASSBs) are gaining more attention due to their advantages, primarily utilizing sulfide as a solid electrolyte. However, several challenges persist, such as decreasing ionic conductivity, increasing internal resistance, and rapid cycle life decay caused by the formation of inactive Na2S, and NaMS2 (M=P/Sb, etc.) byproducts. To suppress Na+ dendrite formation during charge and discharge, make them reversible, and achieve high specific capacity, we aim to implement the strategies proposed in previous literature to enhance electrochemical performance. Methods: In this review, we focus on practical strategies to overcome the challenges of all-solid-state batteries. These include selecting suitable synthesis methods, doping elements to create flexible Na⁺ pathways, applying polymer coatings, and using composite solid electrolytes to suppress Na⁺ dendrite formation and interface reactions at Na electrode sides. We also discuss strategies for improving specific capacity and cell performance by optimizing external thermal and pressure conditions. Sulfide solid electrolytes offer high ionic conductivity and favorable mechanical properties, making them ideal for high-performance sodium-ion batteries. Significant findings: The paper concludes with a call for ongoing research in materials science and engineering to overcome the remaining barriers and fully realize the potential of sodium solid-state batteries. By addressing the outlined challenges and implementing the suggested strategies, development more robust and efficient ASSBs could be developed faster, paving the way for their broader adoption in energy storage technologies. © 2025 Taiwan Institute of Chemical Engineers

The Kuroshio flows with a stable speed (1.0 ~ 1.5 m/s) and direction off the east Taiwan coast. The National Taiwan University (NTU) group developed a 20kW floating-type Kuroshio turbine (FKT) in 2021. The FKT is anchored on the seafloor and floating under the sea surface to utilize the higher current speed on the surface. A physics-based and modular mathematical model is developed to provide dynamic simulation results for the FKT system design and deployment. The usefulness of the mathematical model is in the ability to model the FKT dynamics accurately. A ship towing test was carried out in 2021 to collect FKT data in the current. An estimator based on the EnKF framework was developed to estimate hydrodynamic parameters based on the towing test data. The FKT force/moment balance equations are derived. The estimated thrust coefficients versus tip speed ratio are consistent with results from the towing tests.

Ovarian cancer (OC) is associated with high late mortality owing to hidden symptoms in the early stages and limited screening measurements. Therefore, it is urgent to develop a highly efficient label-free immunosensor for targeting cancer antigens. In this study, we developed a gold-loaded iron-doped nanoporous carbon (denoted as Au@Fe-NC) as an ideal substrate for cancer antigen detection with high specificity and sensitivity. First, an Fe, N-doped nanoporous carbon (Fe-NC) material was synthesized by carbonizing a Fe-doped metal-organic framework at 900 °C under continuous nitrogen flow. The resultant Fe-NC contains pyrrolic-N, which facilitates the auto-reduction of Au3+ to Au⁰ without requiring an external reducing agent. Thus, the Au@Fe-NC was spontaneously formed by mixing an aqueous HAuCl₄ solution with Fe-NC. The immunosensor developed using Au@Fe-NC exhibits outstanding stability as well as high sensitivity to carbohydrate antigen 125 (CA-125), a tumor marker, presenting a linear dynamic range of 0.1 pg mL−1 to 1 µg mL−1 and a detection limit of 0.1 pg mL−1. The proposed Au@Fe-NC-based immunosensor has the ability to detect CA-125 in human serum samples and is a promising material for OC diagnosis. © 2024

Cellulose triacetate (CTA) is commonly used as the material for forward osmosis (FO) membranes due to its good chlorine resistance, fouling resistance and wide availability. In this work, the implications of various solvents on the appearance and desalination performance of CTA FO membranes were systematically investigated. Large pore size and high porosity CTA membranes were constructed by using spray-modified non-solvent induced phase separation (s-NIPS). It has been shown that the water flux of CTA membranes prepared by s-NIPS using dMSO as the solvent was up to 34.4 L m-2 h-1, which was 5.6 times higher than HTI commercial membranes, and the reverse salt flux was only 10.9 g m-2 h-1, which was also lower than commercial membranes. A poly-dopamine (PdA) /graphene oxide (GO) -Fe3+-tannic acid (TA) interlayer was introduced to adjust the cross-linking degree of the polyamide (PA). And thin film nanocomposite (TFN) membranes (PA-PdA/GO-Fe3+-TA-CTA) were fabricated successfully. The water flux was 35.8 L m-2 h-1 and the reverse salt flux decreased to 5.84 g m-2 h-1. These experimental results provide a new way to design and develop high performance FO membranes in a rational way. © 2023, The Authors. All rights reserved.
